I think that the yard capacity is somewhat irrelevant in a lot of cases. =

All of the trucks that haul around here use tonnage as the useful measure=

of the trucks since usually sideboard can be added to the dump box to
increase cu yard capacity. =

Stone weighs about 3000 lbs per yard, so if a 2 1/2 ton truck which is
rated 5000 lbs off road/10,000 lbs on road is loaded to capacity on road,=

it should be able to carry 3 1/3 yards of stone on the road or half that
off road. Of course dirt is lighter than stone so this doesn't apply to
dirt.

The 5 ton dump I have has a 6 yard box, that is, fill it to the top of th=
e
box and you have six yards. So filled to the top of the box it should ha=
ve
about 18,000 lbs of rock capacity. =

Realistically, talking to another guy who has a 5 ton dump, you physicall=
y
can't overload them since the truck is so underrated and the box is only =
10
ft long, even if you put side boards on it you can't get the springs to
seriously deflect even with stone in it. So I suspect it can realistical=
ly
carry at least 8 or 9 yards of stone without to many problems.

I was at a rental shop the other day and they had a 1 ton Chevy dump truc=
k
and they said it will carry about 3 yards of rock. That's about 9,000 lb=
s.
Obviously this is well beyond anything close to a 1 ton rating. So what=

is the realistic capacity of a 2 1/2 ton truck? I don't know, but I bet
that you will run out of horsepower to move the load at highway speeds =

before you run out of weight capacity.
